The ULTTT-1 Ultra-Large Tracked Troop Transport was a model of ground-based troop transport used by the Imperial Army of the Ingzan-Bregaran Empire, captured ones also being used by the AAAIBI. These crawling goliaths were an Ingzan-Bregaran copy of the CMC Digger crawler. The standard model was unarmed but armed models also existed, like the AULTTT-1 Armed Ultra-Large Tracked Troop Transport also there was the ULTSPA-1 Ultra-Large Tracked Self-Propelled Artillery which had the roof taken off so the artillery cannon could rise to firing position (like the SPHA and SPMA, which were later copied by the Ingza and Bregaro as the ULWSPA-1 Ultra-Large Walking Self-Propelled Artillery and the MWSPA-2 Medium Walking Self-Propelled Artillery respectively).
